(Cl. 20G-44) 1 Claim.

This invention relates to improvements in boxes or cartons formed from a single blank of cardboard or other suitable material in which aps integral with the bottom and side walls thereof, are adapted to be folded and interlocked` to form the side wall.

One of the objects of this invention is to provide a foldable display carton with a relatively high rear wall and relatively low end and front walls so that when the top is folded back in a display position the product contained in such carton is displayed above such walls. Another object of'this invention resides in the Alar characters are used to designate like elements.

Figure 1 of the drawing is a plan View of the blank from which the carton of the present invention may be formed.

Figure 2 is a perspective view of closed carton formed from one of the blanks shown in Figure 1.

Figure 3 is a perspective view of a carton formed from one of the blanks shown in Figure 1 with the top folded back in a display position.

The carton illustrated in Figure 1 is formed from a single blank of cardboard or other suitable material scored and cut as shown in Figure 1 and comprises a bottom I, end walls 2 and 3, front Wall 4, rear Wall 5 and top 6 attached to which is front flap 1. Attached to the back of one end wall 2 is ap 8, the outerI end of which is formed into tongue 9 by cut I0. Attached to the back of the other end wall 3 is ap II containing a slit I2 adapted to receive tongue 9 on flap 8. The blank is scored or creased to facilitate bending of the Various elements in the formation of the carton, the bottom I and one end Wall 3 being divided by score line I3 and the other end wall 2 and bottom I being divided by lscore line I4. Other score lines I5, I6, Il and I8 mark the division between the front wall and the bottom, the bottom and the rear wall, the rear wall and the top and the top and the front flap; respectively. The top 6 may contain creases I9 and 20 and slit 2| in order to facilitate the folding of the top to display advertising material behind the product inthe opened carton. Flaps 22 and 23 are integral with front wall 4 and are cut to form tongues on the outer edges thereof, as by cut 24, rounded corner 25 and notch 26 on flap 22, and cut 21, rounded corner 28 and notch 29 on flap 23. A slit 30 is placed in end Wall 2 adapted to receive the tongue on ap 22 and another slit 3l is placed in end Wall 3 adapted to receive the tongue on ap 23.

In the formation of the box, aps 6 and I I are interlocked by the insertion of tongue 9 in slit I2. Front wall 4 is folded to a vertical position and tongue 22 insertedin slit 30 and tongue 23 inserted in slit 3|. The rear wall, top and front iiaps are folded atlcreases I6, I'I and I8 respectively. After the carton has been packedwith the product, top 6 is folded over and front ap 'I is tucked inside of front Wall 4. When the carton is opened to'set up in a display position, top 6 is folded upon itself at creases I9 and 20, and front flap I is tucked inside of rear wall 5. The top 6 may have printed thereon any suitable advertising material, and when folded in the above described display position, will display such advertising material behind the product.

It will be seen that the carton formed in accordance with the present invention has front and end walls substantially lower than the rear wall. When such carton is inthe closed position the front flap operates as the front of the carton and permits the box to be packed with product to a height equal to the height of the rear Wall. When the carton is opened it affords an excellent means of 'displaying the product contained therein as the front and end Walls, being substantially lower than the product contained therein, do not interfere with the vision of buyers while such walls do afford some measure of protection to the display.

The term cardboard as herein used Will be understood to include any flexible material adapted for the manufacture of containers such as strawboard, paperboard, pulpboard, and the like. f
